    • Disclosed is an implantable or insertable medical device comprising (a) a substrate and (b) a hydrogel polymer coating at a least a portion of the surface of the substrate, wherein the hydrogel polymer is adapted to render the medical device visible under magnetic resonance imaging (MRI) upon insertion or implantation of the medical device into a patient. Also disclosed is the use of such a hydrogel coated implantable or insertable medical device in a medical procedure, wherein during or after insertion or implantation of the medical device in a patient, the position of the medical device is viewed under MRI. The use of a hydrogel polymer for coating a medical device wherein the hydrogel polymer is adapted to render a medical device coated with the hydrogel polymer visible under MRI and a hydrogel polymer adapted to render a medical device coated therewith visible under MRI are also disclosed.
    • 公开了一种可植入或可插入的医疗装置,其包括(a)基底和(b)在所述基底表面的至少一部分表面上的水凝胶聚合物涂层,其中所述水凝胶聚合物适于使所述医疗装置在磁共振成像 (MRI)在将医疗装置插入或植入患者体内时。 还公开了在医疗过程中使用这种水凝胶涂覆的可植入或可插入的医疗装置,其中在将医疗装置插入或植入患者体内或之后,在MRI下观察医疗装置的位置。 还公开了使用水凝胶聚合物涂覆医疗装置,其中水凝胶聚合物适于使涂覆有水凝胶聚合物的医疗装置在MRI下可见,并且还公开了适于使其涂覆的医疗装置在MRI下可见的水凝胶聚合物。
